BACKGROUND OF THE INVENTION

Presently (e.g., circa 2017) firearm, tactical training, and/or urban warfare training for law enforcement, military, security, and the like employs various custom built buildings, structures, rooms, hallways, and the like. Often such buildings, structures, rooms, hallways, and the like may be used in non-lethal training, sometimes known as “simunition.” Such buildings, structures, rooms, hallways, and the like may need to stand up to repeated lethal and/or non-lethal ammunition, such as but not limited to, ballistic projectiles like bullets. Different configurations, shapes, and/or patterns of buildings, structures, rooms, hallways, and the like may require different tactics depending upon those configurations, shapes, and/or patterns, as well as on what obstacles, hostiles, and/or hostages may be present in such buildings, structures, rooms, hallways, and the like; and as well as based on mission objectives and team compliments. Presently, building such built buildings, structures, rooms, hallways, and the like is time consuming, labor intensive, expensive, requiring much pre-planning, requiring a diverse variety of building materials, often including separate mechanical fasteners (e.g., nails, screws, bolts, and the like); and also often requires various tools for the assembly or disassembly process.

It would be desirable to minimize the diverse variety of building materials used, to minimize a need to use separate mechanical fasteners, and/or to minimize a need to use tools in the assembly or disassembly process. Such benefits may further be more efficient, reduce time inefficiencies, allow faster planning, and may be less expensive to implement.

There is a need in the art for a system of building customizable structures using just prefabricated panels of a predetermined size along with panel-joiners, and without separate mechanical fasteners and without tools. There is a need in the art for a method of building customizable structures using just prefabricated panels of a predetermined size along with panel-joiners, and without separate mechanical fasteners and without tools.

Additionally, it would be desirable to manufacture a truly customizable, configurable, and modular building system by means of portability by incorporating moving and transportation option such as wheels (casters) or rollers into the system's building elements, such as panels.

It is to these ends that the present invention has been developed.
